  • Numerical modeling on sediment capture in catch basins

    Catch basins are designed to convey surface runoff into sewer systems. They are also found to be effective in retaining sediments. A number of factors can influence catch basin sediment capture efficiency, such as sediment size distribution, flow hydraulics and catch basin design. To better understand the influence of these factors, numerical simulations using the Eulerian-Lagrangian method ...

  • Sampling, testing and modeling particle size distribution in urban catch basins

    The study analyzed the particle size distribution of particulate matter (PM) retained in two catch basins located, respectively, near a parking lot and a traffic intersection with common high levels of traffic activity. Also, the treatment performance of a filter medium was evaluated by laboratory testing. The experimental treatment results and the field data were then used as inputs to a ...

  • Full Scale Evaluation of UpflowTM Filter - A Catch Basin Insert for the Treatment of Stormwater at Critical Source Areas

    ABSTRACTStormwater runoff from critical source areas, such as parking lots, vehicle fueling and maintenance stations, and public works storage areas, may contain pollutant loadings of hydrocarbons, toxic trace metals, nutrients, pathogens, and/or other toxicants and pollutants that are greater than the loadings of “normal” stormwater runoff (Bannerman, et al. 1993;Pitt, et al. ...

  • Asphaltic Concrete Parking Lot

    As discussed we have prepared a capital cost estimate for the two options to pave Whistler Parking Lot 1; one for paving with an 80 mm asphaltic concrete surface and one with a gravel pave surface based on a total area of 6,400 sq. meters. The cost of the paved parking lot includes an oil water and sediment control device (Vortechnics), several catch basins and associated drainage piping. Good ...

  • Porous Bio-Filters - Tools to Fight West Nile Virus

    The year 2002 brought a disturbing upward trend of West Nile Virus cases to the United States, resulting in more than 232 deaths in 2002, just 3 years since first detected within our borders. This virus is carried by mosquitoes, which thrive in pools of stagnant water – large and small. Large bodies of water can be treated rather easily, by adding predators of the larvae, or chemicals. ...

  • Dry cleaning plant: Boston, Massachusetts

    Site Summary Dry cleaning solvents were found in the soil under a parking lot adjacent to a large dry cleaning plant located in a mixed commercial and residential suburb of Boston, Massachusetts. The contamination was traced back to a storm water catch basin in the parking lot which contained sediment and sludge with high concentrations of the dry cleaning solvent perchloroethene (PCE). The ...

  • Peach Processing Wastewater Treatment

    A major fresh pack operation of peaches and nectarines needed a screening system to remove the labels and peach fuzz from their wash water before it was pumped from the pond for irrigation use. Flow to the pond is a steady flow of 50 gpm, rising to 600 gpm during periodic draining of the peach coolers and washing systems. The water is a combination of wash water, labels and fuzz from the fruit, ...

  • Characterization of Iron- and Manganese-cemented Redoximorphic aggregates in wetland soils contaminated with mine wastes

    In wetlands, translocation of Fe and Mn from reducing to oxidizing zones creates localized enrichments and depletions of oxide minerals. In zones of enrichment, oxides cement matrix particles together into aggregates. In this paper, we describe the various Fe- and Mn-cemented features present in the 1 to 2-mm size fraction of mine-waste contaminated wetland soils of the Coeur d'Alene (CDA) River ...

  • A comprehensive approach to reduce disaster risk in which care for people and nature go hand in hand

    Multiple times a year, severe tropical storms and typhoons hit the Philippines. Fortunately, the population is very resilient. After each disaster, they reconstruct their lives with creative solutions. But due to climate change and increasing pressure on ecosystems, the number of natural disasters and their impact are only expected to increase. Working together to better protect communities ...

  • It’s Time to Rethink Cooling Tower Filtration

    ABSTRACTThe dissipation of ambient or process heat in large HVAC systems, manufacturing facilities, power generation plants, refineries, metal mills and forges, chemical plants and food processors is most often accomplished by cooling towers. These simple structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere. The bane of cooling ...

  • Retrofitting an Existing Stormwater System to Meet Numerical Effluent Limits - Stormwater Management at Seattle-Tacoma International Airport

    ABSTRACTOwned and operated by the Port of Seattle, Seattle-Tacoma International Airport (STIA) is the 28th busiest airport in the world. A Section 401 Water Quality Certification was issued to the Port to allow its expansion projects to proceed. This certification required existing portions of the airport be retrofitted to meet current stormwater standards. In addition, the Port’s renewed NPDES ...

  • What is a storm water filtration?

    Water is the main source of living for human beings on this earth. Water is not only essential for human life but also it is a fundamental natural resource for sustaining of wildlife and environment. It is the main substance for surviving a healthy life. There are many vital resources which contaminate the water and many death implications occur. Due to many natural calamities, the water source ...

  • Balancing growth and conservation - Precast concrete manholes become part of the stormwater solution

    When American Fork, Utah, decided to approve construction of a 175-acre commercial center, the city engineers had to consider the environmental effect it would have on a 45-acre wetland right next door. Under the EPA´s Phase II Storm Water Rules, adapted in late 1999, almost any city large enough to require a storm sewer system must balance growth with the environmental impacts of ...

  • Water treatment membrane coating promises chemical-free virus removal

    A novel material coating for water treatment membranes promises to improve the removal of water-borne viruses during treatment. This hydrogel coating, known as a zwitterionic polymer hydrogel, was created by scientists from Ben-Gurion University of the Negev and the University of Illinois at Urbana-Champaign. The virus-fighting membrane was created by grafting the new hydrogel coating onto ...
